AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 347 PM CDT THU JUL 20 2006 .DISCUSSION... MAIN CONCERNS DEAL WITH SEVERE CHANCES LATE THIS AFTERNOON AND TONIGHT...THEN STORM CHANCES ON FRIDAY AND FRIDAY NIGHT. MODEL DIFFERENCES CONTINUE WITH RESPECT TO CONVECTIVE INITIATION TONIGHT...AS WELL AS THE PLACEMENT OF THE SURFACE FRONT FOR FRIDAY AND FRIDAY NIGHT. OUR 18Z SOUNDING SHOWED THE MODELS ARE A BIT AGGRESSIVE WITH THE INSTABILITY IN CENTRAL IL. FARTHER WEST...WHERE THERE WAS BETTER SUN...AND MORE MOISTURE CONVERGENCE AHEAD OF THE SURFACE FRONT...CAPES ARE MORE IN LINE WITH NAM-WRF AND RUC. AFTER DISCUSSION THE CONDITIONS WITH SPC... WILL TRY TO LEAN TOWARD SATELLITE TRENDS AND RUC FOR TONIGHT...AND HIGHLIGHT CONVECTION IN OUR W AND S ZONES. AFTER THAT... NAM-WRF SEEMS IN BETTER AGREEMENT WITH CANADIAN GLOBAL...AND WILL LEAN THAT WAY FOR DETAILS THROUGH MID TERM. SHORT TERM...TONIGHT THROUGH SUNDAY THE SURFACE FRONTAL BOUNDARY IS MAKING PROGRESS TO THE SOUTHEAST ACROSS WEST CENTRAL ILLINOIS. A SURFACE LOW IS BECOMING MORE APPARENT IN THE LATEST SURFACE ANALYSIS IN SE IOWA. THE WHOLE SYSTEM IS EXPECTED TO DROP SE ACROSS OUR CWA. LOOKING ALOFT...THERE ISNT AN OBVIOUS H5 SHORTWAVE SHOWING UP IN THE WATER VAPOR THAT WILL INTERACT WITH THE SYSTEM...BUT RUC FORECASTS ARE INDICATING A VORT AXIS WILL ACCOMPANY THE SYSTEM TONIGHT. OUR SE AREA SHOULD SEE THE CONVECTION ARRIVE SOMETIME LATE THIS EVENING OR AFTER MIDNIGHT. AN AREA OF ENHANCED CUMULUS IS FORMING IN OUR W ZONES...IN AN AREA OF MOISTURE CONVERGENCE AHEAD OF THE FRONT. SPC ANALYZED AND AREA OF MLCAPES OF 2000-3000 IN THAT AREA. EXPECT STORMS TO BEGIN BY 4 PM... WITH A WATCH POSSIBLE AROUND THAT TIME AS WELL. HAVE INCREASED POPS ACROSS THE ENTIRE CWA THIS EVENING...AND KEPT THE AFTER MIDNIGHT PORTION CONFINED TO THE SE HALF OF THE CWA. CORFIDI VECTORS SHOW A MORE PRONOUNCED SE MOVEMENT WITH SUPERCELLS TONIGHT... AND THE PROGRESS OF THE FRONT INDICATES THE BULK OF THE CONVECTION SHOULD MOVE INTO OUR SE ZONES BY MIDNIGHT. FOR FRIDAY...IT APPEARS THE SURFACE BOUNDARY WILL DROP SOUTH OF OUR CWA...BUT AN APPROACHING H5 SHORTWAVE FOR LATE AFTERNOON AND OVERNIGHT WILL BRING A CHANCE OF SHOWERS AND STORMS. THE STRENGTH OF AN EMBEDDED SHORTWAVE IN THE TROUGH ACROSS MISSOURI WILL PRIMARILY AFFECT OUR W AND S AREAS THROUGH SATURDAY MORNING. THE GRIDS ALREADY HAD A GOOD HANDLE ON THAT. DESPITE THE LOWER DEWPOINT AIR AND COOLER CONDITIONS...SUNDAY SHOWS ANOTHER WAVE COMING TOWARD OUR CWA...AND IT HAS BEEN CONSISTENT IN THE PAST 3 RUNS OF THE GFS AND NAM. I ONLY ADDED 20 POPS FOR THE STORMS FOR NOW. LONG TERM...MONDAY THROUGH THURSDAY... MOSTLY DRY CONDITIONS WILL PERSIST...BUT A WARMING TREND IS INDICATED AND WE SHOULD RETURN TO HIGHS IN THE LOWER 90S BY MID WEEK. TUESDAY AND WEDNESDAY HAVE INDICATIONS OF A FEW STORMS DUE TO WEAK SHORTWAVES IN THE NORTHWEST FLOW... BUT ONLY MENTIONED 20 POPS FOR THOSE DAYS AS WELL. && .ILX WATCHES/WARNINGS/ADVISORIES...
